Wesley's Notes on the Bible
They speak vanity every one with his neighbour: with flattering lips and with a double heart do they speak.
The LORD shall cut off all flattering lips, and the tongue that speaketh proud things:
Who have said, With our tongue will we prevail; our lips are our own: who is lord over us?
12:4 Prevail - By raising and spreading evil reports concerning him. Our own - At our own disposal to speak what we please, who can control or restrain us?
For the oppression of the poor, for the sighing of the needy, now will I arise, saith the LORD; I will set him in safety from him that puffeth at him.
12:5 Puffeth - From him that despises him, and hopes to destroy him with a puff of breath.
The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.
12:6 Pure - Without the least mixture of falsehood; and therefore shall infallibly be fulfilled.
Thou shalt keep them, O LORD, thou shalt preserve them from this generation for ever.
12:7 Thou shalt keep them - Thy words or promises: these thou wilt observe and keep, both now, and from this generation for ever.
The wicked walk on every side, when the vilest men are exalted.
12:8 Walk - They fill all places, and go about boldly and securely.
